The powerpc kernel maintains information about logical memory blocks in the lmb.memory structure, which is initialized and updated at boot time, but not when memory is added or removed while the kernel is running. This adds a hotplug memory notifier which updates lmb.memory when memory is added or removed. This information is useful for eHEA driver to find out the memory layout and holes. NOTE: No special locking is needed for lmb_add() and lmb_remove(). Calls to these are serialized by caller. (pSeries_reconfig_chain).
